# Note: [Nix Flake Usage]:
#
# The flake location can be defined as:
#   `github:change-metrics/monocle`, or `path:/absolute/path`, or `.`
#
# Package output can be accessed using their #name:
#   nix show-derivation '.#containerMonocle'
#
# For non packages, the full qualified name can be used:
#   nix show derivation '.#devShells."x86_64-linux".ci'
#
# Inspect context using nix-tree, for example:
#   nix run github:utdemir/nix-tree -- --derivation .#devShell."x86_64-linux"
